$AFETY ATTACHMENT FUR GINS...

SPECIFICATION forming part of Letters Patent No. 776,007, dated November 29, 1904. Application filed March 8, 1904. Serial No. 197,089. (No model.)

To (bl/Z whom, ii; may concern:

Be it known that I, WILLIAM SoRNeY BAKER, a citizen of the United States, residingv at Purves, in the county of Erath and State of Texas, have invented new and useful Improvements in Safety Attachments for Gins, of which the following is a specification.

In the ginning of cotton great care and attcntion must be exercised in watching the condenser which removes the fiber from the lint- .iiue into the press-box. Stoppage of the con denser from any cause, such as a broken belt or chain, &c., will result in damage by breakage of some of'the parts or by fire from the friction of the gin-saws through the cotton.

The object of my invention is to provide means whereby when from any cause the condenser slows down or stops running the breast of the gin will be automatically lifted, so that the saws will no longer operate on the cotton, and at the same time the feed of cotton to the saws will be stopped.

With these objects in view the invention consists in certain novel features of construction hereinafter described and claimed, and shown in the appended drawings, in which Figure 1 is a front elevation of a saw-gin provided with my improvements. Fig. 9. is a side elevation thereof. Fig. 3 is an enlarged detail view in perspective of a part of the attachment.

Referring specifically to the drawings, A denotes the gin-saws. They are mounted on the usual saw-shaft, which is supported, in suitable bearings on the main frame a of the machine, and driven from any source of power. The usual brush for removing the lint from the saws is indicated at B. Hinged to the front of the gin at c is the gin-breast G, carrying the usual gin-ribs, between which the saws revolve when the parts are in operative position.

The parts thus far described are of the usual construction and are all to be found in ordinary saw-gins.

In front of the gin below the breast a rockshaft D is mounted in suitable bearings d on the frame a. This shaft extends throughout the entire length of the gin and carries wipers A, which extend under the breast, at each end thereof, in such a manner that when the shaft is rockedsaid wipers will lift the breast away from the saws, whereby they will be rendered inoperative. By means of a handlever A, secured at any convenient point on the shaft. the wipers may be manually operative, if desired. On one end of the shaft D there is secured by a set-screw 1) or otherwise a downwardly-extending lever D which carries as its outer end a rod D which is joined to another rod, D by a connection comprising loops D and 1) on the latter rod, through which the rod D extends. The latter rod has on its outer end an enlargement or nut 1", so that the parts cannot become separated. The purpose of this construction is to permit the gin-breast to be lifted by the hand-lever A without disturbing the mechanism which actuates the rod D. It will be seen that when the hand-lever A is swung forward-to lift the gin-breast the upward movement of the rod 1) will not be communicated to the rod D as the former will simply slide through the loops D and D; but when the rod 1) pulled up the loop D thereon will catch behind the enlargement D, whereby the rod l.) will move with the rod 1) and the shaft I) will be rocked, causing the wipers to lift the breast, as heretofore described.

I will now proceed to explain the mechanism for automatically operating the parts just described. This mechanism is controlled by a governor in gear with the condenser, the construction being such that the breast will be lifted when the condenser steps or runs too slow for a safe operation of the gin. On a bracket or ')latform E, extending from the wall of the gin-room or located in any other convenient position, is mounted a pillow-block F, having bearings F and F. A shaft (ar is mounted in the bearing F and has at one end a movable clutch member r which is movable along the shaft to engage the fixed clutch member r/ on a shaft G" in the bearing F, whereby said shafts arecoupled. The shaft G has a pulleyH, which is driven by a belt H from a pulley l1 on a line-shaft /z. The shaft G carries a disk 1, near the rim of which the rod D is secured, as at D, in any suitable manner. This dish is to be driven from the shaft Gr bycoupling the same to the shaft G, as heretofore described, and operates the rod D to raise the gin-breast. A portion of the condenser is shown at K and the drive-shaft thereof at K. On said shaft is a large bevelwheel is, which is in mesh with a small bevelwheel it" on a shaft k", which drives a ballgovernor L of ordinary construction, which is mounted on the pillow-block. To the governor-stem L is pivoted one arm of a bellcrank lever Z, the other arm of which is pivoted to a block Z, which is loosely mounted in a groove 6 in the movable clutch member g. The bell-crank is fulcrumed to a suitable support Z on the pillow-block. It will be seen that when the governor-stem drops by reason of a decrease in the speed of the condenser the clutch member y will be slid forward into engagement with the fixed clutch member on the shaft G, causing said shaft to revolve and the disk I to turn, which will actuate the rod D to lift the gin-breast. In order to operate the clutch manually, a rod M is connected to one arm of another bell-crank m, fulcrumed on a support an on the pillow-block. The other arm of the bell-crank is pivoted to the block l. The rod extends to a convenient location near the gin and has a handle, whereby it may be readily grasped by the ginner to operate the clutch.

In addition to the above means must also be provided for holding up the gin-breast until the necessity for the stopping of the gin is removed. This is accomplished by forming a cam-like projection N on the face of the disk I. A follower N is connected at one end to the block Z, and the other end has a roller h in contact with the projection N, so that when the disk is revolved a certain distance, depending on the length of the projection, said follower will be moved sidewise in a plane parallel to the axis of the shafts G and G and being connected to the block Z the clutch member Q will be disengaged from the clutch member g, which stops the shaft G and the disk I. The follower is mounted in suitable bearings on a support N extending from the pillow-block.

After the shafts are uncoupled it will be neces- 1 sary to hold the disk I from turning back, and

thus lowering the gin-breast again. This is accomplished by a dog 0, pivoted on the pillow-block, which engages behind a projection l 0, formed on the rim of the disk I. The con- 3 nection between said disk and the gin-breast is so adjusted that when the disk has made one-half a revolution the gin-breast will have been sufficiently lifted to render the saws inoperative. The cam projection N is also so constructed that when this half-revolution of the disk has taken place the shafts G and G will be uncoupled and at the same time the dog 0 will have engaged the projection O, thereby holding the disk from turning back. A rod 0 is secured to the dog and extends to a convenient location near the gin, having a handle whereby it can be grasped by the ginner to release the dog. hen this is done, the disk I can turn, and the breast will drop down to its normal operative position by reason of its own weight.

The mechanism described thus far only lifts the gin-breast to render the saws inoperative. In addition to this it is advisable at the same time also to stop the feed of cotton to the gin. This is accomplished by the following means: The feeder is indicated at I and the feedershaft at Q, on which there is a pulley R, which receives motion from the saw-shaft by a belt S over a pulley T on said saw-shaft. The belt is a loose one and is kept in operative position by a tightener, which consists in an idler U, which is journaled in a fork V, which is secured at its lower end to a lever IV, fastened on the rock-shaft D by a set-screw or other suitable manner. It will be seen that when the shaft D is rocked the idler will be thrown off the belt, whereby it is loosened and rendered inoperative, thus stopping the feed of cotton to the saws. hen the shaft is rocked in the opposite direction to resume operation of the gin, the idler will again engage the belt and tighten it, whereby the feed of cotton will be resumed.

I have shown and described the attachment connected to one gin only. Inasmuch, however, as gins are usually operated in series of several, it may be desirable to have the-device operate on all the gins simultaneously. This can be done by extending the rock-shaft along all the gins and providing wipers thereon for each gin-breast. If the entire series of saws are mounted on one shaft and the feeders also, the belt-tightener mechanism need not to be duplicated.

It will be further understood that changes in the minor details of the construction may be made without departing from the principle of the invention. \Vith slight changes it can be readily installed in any ordinary saw-gin plant.
